Hello,
I need to restrict EXIM smtp response to only mail relay clients defined in
relay_from_hosts. I need EXIM server to reject/drop any smtp connection
from any servers other than loaclhost or mail relay clients (IPs or
hostnames).
I restrict relay to client IPs allowed to relay. I have one file for relay
clients IPs and one for hostnames : /etc/exim/relay_hosts and
/etc/exim/relay_ips.
I tried different variations of ACL below with no luck.
Any feedback is appreciated
Thanks
acl_smtp_helo = acl_check_helo
hostlist allowed_helo = lsearch;/etc/exim/relay_hosts
acl_check_helo:
hosts = +allowed_helo
deny message = Not authorized relay to connect .
log_message = Reject non relay
deny condition = ${lookup
{$sender_helo_name}lsearch{/etc/exim/relay_hosts}{yes}{no}}
accept
